On his way back from the NATO Summit in Newport, Obama decided to swing by prehistoric Stonehenge.
He spent more than 20 minutes within the site.
Obama spent about 20 minutes walking around Stonehenge, declaring it "spectacular" and saying he had knocked this off his bucket list.
He was even able to get right up close to the stones.
So every person who has visited Stonehenge before is feeling a little bit hurt right now.
Oh it's ok for Obama to wander all through Stonehenge - us poor old members of the public can't get within 10 feet of it!
Obama gets to walk around Stonehenge & stuff but when *I* turn up naked with a sacrificial goat it's all policemen and tasers and questions.
And of course as Stonehenge is right next to the frequently congested hellhole called the A303.
Everyone is wondering how on earth he got there.
#Obama must be some kind of mentalist. What dick takes on the A303 on a Friday evening to visit #Stonehenge ? It must have been gridlocked
I wonder how Obama found the A303 on his way to Stonehenge? Perhaps, like me every time I drive down it, it was a complete toilet?
How the hell did Obama's motorcade get past the 5-mile tailbacks on the A303? Come on, we're all thinking it. #Stonehenge
President Obama has clearly never gazed upon Stonehenge while stuck on the A303 in single-file traffic on the way to a wedding.
One determined family decided to go to Stonehenge to see what the fuss was about.
@AnniePats president Obama is at Stonehenge x
Can't believe I'm walking to Stonehenge to see if the rumours are true!!
I can see president Obama! Any messages?
He waved to us!!
Which led to this photograph being taken.
The tweeter Janice Raffle told ITV News "at that point he shook our hands and asked if we lived in the area... he asked our names too as he's a polite man."
